High technology for motors driving. WEG VSDs offer several features like easy installation and operation, compact size and have a number of special functions. Available in power ratings from 1.1 to 1,100 kW.

 

Description

The WEG CFW-09 Series of Variable Speed Drives incorporate the world’s most advanced technology in drives for three-phase AC induction motors.

 

The Vectrue Technology™ represents a siginificant advancement, allowing this new generation of WEG inverters to combine V/F, Sensorless Vector and Closed Loop Vector (with encoder) control techniques, all in one product.

 

An innovation was also introduced to simplify applications that require braking torque. A new feature named Optimal Braking™ eliminates the need for the dynamic braking resistor in some applications allowing a simpler, more compact and economic solution.
